provedV Umbrella Safety Device, of which` the following` is a full, clear, andeXact description.

' This invention relates generally to a safety devicefor umbrellas and *more specifically to stop memberadapted to be positionedl uponfthe main rod or staff of the umbrella tojprevent the umbrella from being turned inslde-out when usedin high winds.V

One of the objects of this ,invention is to provide a safety stop adapted to be posi` tioned upon the upper portion of the um- `V`movement of the sliding 'collar carrying,

` brella stem.

Another object of this invention is to pro-` vide a stop adaptedto be. positioned on the main umbrella rod orstaff to limit the the bracing ribs, and to further function creased` strain thrownupon these bracing'y members will be taken from the endsof the` asa stop or supportwith which the bracing ribs. may directly Contact, thus acting as a direct support therefor, so that the inbracingribs where they. are wired or seated within the sliding` collar.

A further Objectis to 'l provide la detachablesafety ystop-for an: umbrella which is readily adaptedto be applied to umbrellas already in use, the stop being so constructed as to occupy but little space when the um# brella is closed, but yet furnishing ample bearing space upon the umbrella rod andV having a projecting shoulder which will eHectively serve to act as a direct stop for the bracing ribs, thus relieving the strain from the ends of said ribs, as above noted.

A further object of this invention is to provide a stop which is simple in construction and inexpensive to make and which is readily adapted to be applied to 'any um'-` has been found that invariably when an umbrellahas turned inside-out in heavy winds, thef ribs havel given way at the point of connection, so therefore, in the present invention' there is provided aY stop member 4positioned on the umbrella staff or stem between the, slidingl collar. and the end of the umbrella, there beingy provided for said stop `a projecting vshoulder which will furnish a direct support for the bracing rods between the ends thereof, thus relieving the extrastrain'and tension at the ends of the said bracingmembers carriedin the sliding collar.

In the accompanying drawings showing one preferred form of the inventionsimilarcharacters of. reference designate like parts inthe several views.

Figurel is aview of'an umbrella shown in raised position with the stop positioned therein.

Fig., 2 is a broken elevation view partly in section showing more clearly the position and character ofthe stop.

Fig. 3 is a sectional plan view taken on the line 3 3 of Fig. 2.'

Fig.V e is a broken elevation view partly in section-showinga modified form of stop member having a raised bead around the` edge ofthe projecting shoulder ofthe stop. In. the, accompanying drawings showing one of thepreferred forms of the invention,

the stop member is shown as comprising two parts l, 2, connected together by screws 3 or other suitable means, there being an Opening extending through the center thereof so that the parts may be positioned upon an umbrella staff or stem 4 which may be of the ordinary type.

One part 1 of the stop comprises `a semicircular annular member 5 having a shoulder 6 at one end and extending therearound, the other part 2 comprising another semi-circular annular ring formed to lit with the first portion and form a continuation of the shoulder 6, the inner semi-circular annular portion being cut away to form a flat surface to receive the heads of the screws.

A stop member is shown in Fig. 2 as being positioned on the stem 4 between the usual spring catch 7 and the usual collar 8 in which is carried one end of the umbrella ribs 9. The usual sliding collar` 10 is provided, in which is secured the ends of bracing ribs v11 of the umbrella. The ends 11 of the bracing rods are usually secured to the collar 10 by passing a wire 12 around Y the collar andthrough openings in the ends of the bracing rods l1.

It is understood that there is no claim here made to the particular construction of the umbrella, the construction of the parts above enumerated being well known in the art.

One of thc important features in the construction of the stop is that the shoulder (3 should extend a sufficient distance from the stem 4 so that when the umbrella is raised7 in which position the collar 10 will rest upon the spring catch 7, the outer edge 13 of the said shoulder 6 vwill contact with the bracing ribs 11 between the endsthereof, as at a point inward from the point of support 12, and will act as a rest or support for said bracing ribs 11. Thus it is seen that the main strain is relieved from the ends of the bracing ribs at the point of connection l2 with the sliding collar 10 and is taken up by the shoulder 6 of the stop.

A modified form of the stop is shown in Fig. i in which a bead or ridge 11i is formed at the edge and on "the under side of the shoulder 6. The position of the parts are shown in the positions which they would occupy when heavy winds are blowing. The stop 5 is shown in this view as being spaced a greater distance from the spring catch 7 than that shown in the other figures. When the stop is so positioned, the sliding collar l0 under normal weather conditions will rest upon the spring catch? and the bracing ribs il -will be out of engagement with the edge ofthe shoulder 6 lof the stop, but, when heavy 'winds prevail, there will be tendency for the ribs 9 to spread outward, thus carrying the sliding collar l() toward the end of the staff 4, thus bringing the ribs 1i in contact with the shoulder 6 of the stop.

The stop is preferably made of metal or other suitable material.

It is understood that certain changes and modifications of the preferred` form herein shown may be made without departing from the spirit and scope of this invention, the improved feature being the provision. of a stop adapted to be positioned on the umbrella staifto function as a' stop or support for the bracing ribs.

Having thus described the invention, what I claim as new is: y Y

l. In an umbrella, comprising Aa staff, a collar sliding thereon and bracing ribs connected with said collar, a rigid stop detachably mounted on the stai at the upper end to act as a stop having a projecting portion positioned tocontact with the brac- Y mg ribs between the point of connection with the sliding collar and outer end.

2. ln an umbrella, the combination of a stall', a sliding collar therefor, bracing ribs connected thereto, a spring catch for said collar and a stop member positioned on said staff between the end of the staff and the spring catch to contact with the bracingribs between the ends thereof to act as la stop to limit the movement rof the bracing ribs.

3. As anv article of manufacture, af stop adapted'to be rigidly positioned on the staff of an 'umbrella at one end thereof, the said umbrella having a sliding collar and bracing ribs connectedy to said collar, the said stop having a shoulder which comes in direct Contact with and acts as a support for thebracing ribs intermediate their ends.

il. As an article of manufacture, a stop member adapted to be rigidly positioned on the staff of an umbrella to come in direct contact with the bracing members thereof, the said stop comprising a plurality of parts each having a shoulder portion for bracing the ribs, and a means for securing said parts upon the staf in fixed-relation.
